i wouldn't use anything from gillette even if they paid me. And BTW Skinguard is not able to shave very close due to the mechanics of the carts itself. I know it's intentional..but i am not willing to pay 20 euros for a pack of 4 that shave LESS close of the older ones. I would stick with the older type or better move to safety razors. And the latter is exactly what i'm doing now
